Taming is basically becoming a friend with an animal. Its hard to implement. But I like the idea, hunters become more stronger because they can hunt with tamed animals, but also getting a Rivnak by taming would be a great idea, I guess you could almost learn how to sell them as well and use the idea of Rivnak taming to make tria, of course it will probably need to be a highly skilled person in Taming since you need to tam the Rivnak to trust you and other people to sell it on.
